In 2012, Seiko took electronic watchmaking to a new level with the Astron GPS Solar, a watch connecting to the GPS network and adjusts, with atomic clock precision, to every time zone* at the touch of a button, while taking all the energy it needs from light alone. In 2021, Seiko teams up with KOJIMA PRODUCTIONS to create an Astron watch that fuses the Dual-Time 5X53 Caliber with a design inspired by their signature icon Ludens.

Astron GPS Solar and the celebrated Japanese game creator Hideo Kojima are natural partners. Just as Astron has pushed back the frontier of high technology watchmaking with a continuous series of ever more advanced calibers, so KOJIMA PRODUCTIONS has created in “DEATH STRANDING”, a game which opens up a whole new genre of gaming experience. It won the “PC Game of the Year” at the Golden Joystick Awards 2020, one of the most prestigious awards in the industry.


KOJIMA PRODUCTIONS is a creative studio led by game creator Hideo Kojima established in Tokyo, Japan in December 2015 under the slogan FROM SAPIENS TO LUDENS. The studio’s first game “DEATH STRANDING”, which featured world-renowned actors, was released on November 8th, 2019 for PlayStation®, and the PC version followed on July 14th, 2020. The title has received accolades from around the world and won numerous awards since its release.

A design infused with the spirit of Ludens

This watch’s design incorporates several design elements inspired by Ludens’ suit and the interwoven pattern on the dial reflects the texture of his carbon face mask motif. Gold color accents echo the metal parts of the suit, including the interlocking design of the two sub-dials. The iconic studio logo is printed both at the 9 o’clock position and on the case back. On the bezel, the UTC codes are in the same font as KOJIMA PRODUCTIONS’ logo and the studio’s signature FROM SAPIENS TO LUDENS is discreetly engraved on the bezel side at the 6 o’clock position.

The interlocking sub-dials are inspired by the hinges of Ludens’ suit. The cut-outs in the hour and minute hands echo its flag spear’s design.

The watch connects up to twice a day to the GPS network to maintain its precision**, it adjusts automatically to Daylight Saving Time*** and, when the wearer changes time zone, he or she simply pushes a button and the hands move to the correct local time, thanks to the system that moves the hour, minute, and seconds hands independently. Caliber 5X even gives the wearer the ability to change the main time display instantly from home to local time and vice versa.

The watch is offered as a limited edition of 1,000 and will be available at selected Seiko Boutiques and retailers in June.

* If there are changes in the region / time zone / DST, manual selection may be required.
**When the watch dial perceives sunlight, the watch connects to the GPS satellite network and adjusts automatically to the correct time. If the watch is hidden from light, it remembers the time of its last successful manual connection and attempts to receive the GPS signal again at that same time.
***When the time zone adjustment is successful, the watch will display local DST. This will not apply when time zone is selected manually.

The case back carries the serial number and it is presented in a special box which includes a message card from Hideo Kojima himself and the art director of the company.
